cnnnsmc MECHANISM ron'snnnr COLLECTING nun FOLDING nnonnvnsfi To all whom it may concern: 1 v

.Be it known that I, HOWARD M. BARBER, a citizen of the United States, andresident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Greasing Mechanism for Sheet Collecting and Folding Machines, of which the following'is ,a specification. l The object of my invention is to provide means for creasing partially folded signatures so that when the signatures are finally folded, cut, gathered and secured together, the product thus formed will r eadily'lie open at any particular'page. i

A further object is to provide means for creasing a transversely folded i signature longitudinally of its-travel upon-one or both sides of its longitudinal fold line before its longitudinal fold is made.

A still further object is to provide means for reversely creasing the partially folded signature upon one or both sides .of the longitudinal fold line so that the leaves will readily fold back either way along the A practical embodiment of the invention is represented in the accompanying drawings, in which, v f Figure 1 is a view in side elevation of so much of a sheet collecting and folding machine as includes my invention.

Fig. 2 is a vertical section taken within and adjacent to the near side frame of the machine.

Fig. 3 is a partially inverted'plan view showing the creasing mechanism.

Fig. 4: is avertical section taken just inside the far side frame.

Fig. 5 is a detail diagrammaticsection taken centrally through the Inachine'from front to rear.

Fig. 6 is an enlarged diagram showing the result of the first set of creasing rolls, and" Fig. '7. is a similar view showing the result of the second set of creasing rolls.

The two side frames of the machine are denoted by 1 and 2. The web feed mechanism is denoted by 3. The pair of rotary cutters 4, 5 have shafts 6, '7, which cutters are, in the present instance, shown as provided with one set of 'coactingblades 8*," 9, arranged to cut the web transversely into one sheet forea'ch revolution-of the cutters.

Specification of Letters Patent.

The sheet collectingicylinder 10 has a:- shaft '11, which cylinderis herein shown as provided with one set of grippers 12.]

This collecting cylinder.-10' also acts as a folding-06. cylinder. audit is provided with artucking blade 13 arranged-to coact in the. present instance, every two revolutions of jaws lt carried by the female folding cylinder 15.the shaft of which is denoted by 16.

A I p Patented Oct. 23,1917. .Application filedDeceniber 19,1914. Serial No. 878,153. I I Y the collecting cylinder 10 with the folding This folding mechanism imparts a fold to thesignature transversely to its travel. The.

folding mechanism herein shown on the cylinders 10 and 15 is of the well known I floating folding blade and jaw type, andthe cylinder 15 is shown as making OIlflIGVOlH- tion to two. revolutions of the collecting cylinder. 10. I '1 p t w I A cylinder 17 is mounted on a shaft 18, which cylinder in p the I present instance, serves asa slitting cylinder and as a first creasing cylinder. This cylinder is provided with aset of grippers 19 arrangedto receive-the first-folded signature from the cylinder 15 and transfer the same to the grippers 20 on the cylinder 21, the shaft of which is denoted by 22. The grippers 2,0" are arrangedto transfer the transversely folded signature to the grippers 23 on the delivery cylinder '24, the shaft of which is denoted by 25. This cylinder 24: is arranged todeliver-thefsheet on to the folding table 26 by any suitable means, such as the two sets of endless tape carriers 27, 28, Onthis table 26, the transversely folded signature is folded longitudinallyof its travel by the usual folding blade 29-and coacting jaws30.

The cam mechanisms for insuring the proper opening and closing ofthegrippers on the cylinders 10, 15,'1,7,and 24; the cam mechanism for insuringthe folding oflof Y the collected sheetsfromthe cylinder 10 to the cylinder 15, and for controlling the floatingof the tucking blade and folding jaws, and the mechanism, (not shown, for controlling the operation of'the foldingmechanism for impartingthewlongitudinal-fold to the transversely nfolded signature, will not be specifically described herein as they maybe of anywell known orpapproved form and are not a part of the' present invention, which invention is directed to the creasing of the partially ;f,olded signatures, the mechanism fonwhich will now be described.

, The cylinder. 21, as shown, isone-half-the totransfer the advance edge of the signature to the"grippers 23. This is accomplished by a rocking cam arm 5?, carrying the cams 58, 29, which arm is controlled by a' box cam on the shaft 25 of' the cylinder 24, through the connecting rod 61 and rocking arm 62. i

First creasing disks 31, 32, 33. are'shown as coacting wit-h the cylinder 17, the disk 31 being arranged to crease the transversely folded signature longitudinally of its travel along its longitudinal fold line so as to facilitate the folding of the said signature longitudinally of its travel on the-table 26. The creasing disks 32,33, are arranged to coact with the cylinder 17 to produce the first creases longitudinally of the travel of the transversely folded signature upon the sides of and parallel withthe longitudinal fold line and at predetermined distances therefrom. Second creasing disks 34, 35 are arranged to coact with the cylinder 21 to reversely crease the transversely folded signature longitudinally of its travel along the first creases formed by the creasing disks 32, 33. The creasing disk 31 is supported from'a crossbar 36. The creasing disks 32,

33 are supported fromthe crossbar and,

the creasing disks 34,35 are supported from a crossbar 38 If so desired, the transversely folded signature n ay be slit longitudinally of its travelinto any number of smaller signatures by one or'more slitting disks-39, supported from the crossbar 36. it being understood that the sets of creasing disks correspond in number to the number of smaller signatures which are slit from the transversely folded signature by said slitting disk'or disks 39. In the present instance, I have shown one of these slitting disks 39'mounted on a cross shaft 40, and I have shown twosets of creasing disks, the disk 3l being mounted on a cross shaft 41, and the disks 32, 33, 34, 35, being mounted on cross shafts 42,43, 44, 45 respectively. 7 r

The several rotary parts are interconnected to move at the desired relative speeds through a'train of gearing 47,48, 49, 50, 51, 5e, 53, 5c. 1 I I wish it understoodthat 'by'the term cylinder I contemplate anysuitable means for carrying the sheets-through'the prescribed paths, and by the-term grippers I contemplate any suitable means for engaging said sheets. 7 In theembodiment of the-invention shown and described-herein, the operation of the machine is-as follows: The 4 Web as it comes upon opposite sides thereof. "Each trans-- versel folded si nature is'then transferred to the cylinder .21 where the. creases .npon

opposite sides of the longitudinal foldline arereversely. creased. .The thus creased sig-v natures are then transferred to the cylinder 24, and delivered-on to the folding-table 26,

where each signature is folded longitudi nally of its travel along the crease between the two reverse creases. I

This reverse creasing of the signature adjacentto its longitudinally foldededge and parallel therewith, will permit each of the leaves to be readily turned back and forth on the said reverse crease asa hinge, permitting the product formedfromh'ansignatureroricollected group. of signatures to be readily openedand when, ope tolie flat t any particular portion thereof. 7

It is evident-that various changes may be resorted to in. the construction, form and arrangement of the various-parts Without departing from the spirit. and scope of my invention and hence I do not Wish to limit myself strictly to the construction herein set forth, but r What I claimis: I
